The movement of waves on the surface of a fluid is always accompanied by a displacement of the particles in the wave propagation direction, this is the Stokes drift. This phenomenon can be found in aluminum electrolysis cells. More or less regular oscillation animates the interface between the electrolyte bath and the metal in a cell. It is well known that material, such as rafts of alumina and solidified bath, particles of undissolved alumina, cryolite snow can float on the metal bath interface. So these can be transported by waves at the interface. The purpose of this paper is to review the literature on the works already done on the study of surface waves, interface waves and Stokes drift. Then the mass transport induced by these waves will be estimated for the case of the metal bath interface in the electrolysis cells.
